On December 12, Hithium unveiled the world’s first native 8-hour long-duration energy storage solution—∞Power⁸ 6.9MW/55.2MWh. This solution is built on an underlying 8-hour energy storage system architecture and supported by dedicated 8-hour battery cells. With a native design from cells to the system, it represents the industry’s first true 8-hour long-duration energy storage solution, heralding the dawn of the all-weather green energy era.
Currently, electricity demand from sectors such as electric vehicles and data centers is rapidly increasing, driving a global energy transition toward variable renewable energy sources. However, a fundamental conflict exists between the intermittency of renewable energy generation and the stability and flexibility required by power systems, making 2–4-hour energy storage solutions insufficient to meet system balancing needs.
Against this backdrop, 8-hour long-duration energy storage, which enhances grid stability and improves renewable energy integration, is emerging as a new direction for the energy storage industry. Compared to 2–4-hour energy storage cells, dedicated 8-hour energy storage cells offer superior system integration and higher economic efficiency, making them a better choice for long-duration storage scenarios and aligning more effectively with all-weather, multi-scenario energy storage demands.
As a pioneer in the lithium battery long-duration energy storage sector, Hithium continues to drive technological evolution, striving to achieve unparalleled cost competitiveness in energy storage. This further solidifies the advantage of lithium batteries in the long-duration storage market and accelerates the transition of lithium battery long-duration storage toward large-scale, widespread application.
